The introduction of Perfluorochemicals into medicine and especially into the treatment of severe lung injury is a fascinating scientific task. Many recall the famous experiments from Clark et al. in 1966 when he demonstrated "liquidventilation with perfluorocarbons" in the mammal species for the first time. After this hallmark, perfluorocarbons were subsequently introduced in research of acute lung injury by the techniques of Total- and Partial-Liquid-Ventilation (TLV; PLV). ⋯ These questions need to be clarified before this technique can be applied clinically. However, the inhalation of vapor, a technique already familiar to anaesthesiologists should avoid risks of large amounts of fluids in the bronchoalveolar space. Furthermore, this technique can be administered by established anaesthetic equipment with the advantage of exact dosing, continuous monitoring, and demand application in a way near to clinical routine.

Decompression injuries are potentially life-threatening incidents, generated by a rapid decline in ambient pressure. Although typically seen in divers, they may be observed in compressed air workers and others exposed to hyperbaric environments. Decompression illness (DCI) results from liberation of gas bubbles in the blood and tissues. ⋯ The most important therapy, in the field, is oxygen resuscitation with the highest possible concentration and volume delivered. The definitive treatment is rapid recompression with hyperbaric oxygen therapy. Additional therapeutic measures are discussed.
